The effect of Ammine and Wyamine on the depressed circulntion in acute cardiac tamponade was studied in six dogs. As u result of tamponade, there was marked depression of the apparent right and left ventricular function curves which were then significantly re-elevated by the administration of these drugs. Evidence of coronary insufficiency was demonstrated in very severe tumponudo where there w...

The known five-coordinate, square-pyramidal, green trans-RuCl2(P-N)(PR3) complexes (P-N = o-diphenylphosphino-N,N'-dimethylaniline; R = Ph (1a), p-tolyl), in the solid state at ambient conditions, or in CDCl3 solution at low temperatures, coordinate CO (at 1 atm) to form beige-coloured trans-monocarbonyl derivatives. In the solution reactions at room temperature, the PR3 ligand dissociates and ...

The potential energy curve describing the fragmentation of a diatomic dication ABZ+ is considered as arising from an avoided crossing between an attractive diabatic curve (correlating with A' + B) and a repulsive diabatic curve (correlating with A+ + B'). The simplest avoided-crossing (AC) model neglects diabatic coupling and polarization and leads to useful predictions of the transition struct...
